Ok, so, recently I have been analyzing Jet's character because of my "Sonic fever", and I feel he should be here.

What's The Work?
Sonic the Hedgehog is a world-famous video game series created by Sega in 1991.
Who Is He?
Jet is a minor antagonist/ally of the series, first appearing in Sonic Riders, he is the leader and youngest member of the series and Sonic's third rival.
What Makes Him a Shonen Rival?
Anti-Heroic: Jet has put aside his rivalry with Sonic sometimes to defeat worse threats such as Eggman and the Babylon Guardian.
Honorable: Jet has shown a rather honorable side, at one point praising Shadow and Rouge's skills.
Arrogant/Jerkish: Jet is extremely cocky and a massive jerk, with a snide sense of humor
Pursues a Big-End Goal: Jet wishes to acquire as much wealth as possible.
Short-Tempered: Jet is extremely wrathful, and can throw fits over petty things.
Spiky Hair: Jet has spiky-mohawk like feathers on his head.
Unnatural Hair Color: Green.
Verdict?
Yes for Jet. While he is not as notable as Shadow, he still meets the criteria.
